DESCRIPTION OF WESMAELIA CREMASTA, A NEW BRACONID FROM 
GREAT BRITAIN AND SPAIN. 
BY THE REV. T. A. MARSHALL, M.A., F.L.S. 
Gen. WESMAELIA, Forst. 
Verh. nat. Ver. d. pr. Rheinland, 1862, p. 235. 
First cubital cell separated from the discoidal. Antenne not cla- 
vate. First segment much elongated, linear. 
The above are all the characters given by Forster for this genus, 
belonging to the group of Huphorus and Microctonus among the Braco- 
nide. It may be immediately recognised by the remarkably long and 
slender petiole, resembling that of Pelopeus, but curved.  Forster’s 
type, W. pendula, is undescribed, and may very likely be the same as 
the following species. The practice of issuing such names is of course 
perfectly useless, and should be discontinued. 
WESMAELIA CREMASTA, sp. 7. 
Testacea, mandibulis apice et metathorace, interdum rufis ; oculis, 
ocellis, meiathorace postice, terebreque valvulis, nigris; antennis tar- 
sisque, apice fuscescentibus. Long. 1% lin. 2. 
Head large, wider than the thorax, sub-cubical, buccated; occiput 
hardly emarginate. Antenne nearly as long as the body, 26-jointed, 
slender; the joints cylindrical near the base, becoming moniliform to- 
wards the apex. Mesothorax trilobate, gibbous, much higher than the 
prothorax. Scutellum slightly convex, rounded at the apex, and having 
a shallow transverse fovea at the base. Metathorax short, descending 
rather abruptly, excavated behind in the middle, rugulose, without 
areolets. Wings hyaline, nervures and stigma testaceous, the latter 
edged with brown beneath; radial cell lanceolate, larger than in the 
allied genera, with which the neuration in other respects agrees. First 
segment of the abdomen not thicker than the hind femora, as long as 
all the other segments together, linear, regularly curved, very slightly 
widened at the middle, where the spiracles are situated; segment 2 
concealing all after it except the apical. Abdomen small, strongly 
compressed ; viewed from above, linear-ovate, acuminated at both ex- 
tremities, smooth, shining ; viewed laterally, pyriform. Terebra short, 
curved upwards. Legs elongate, slender. Testaceous, the clypeus 
yellow, with whitish hairs; the mandibles in one specimen rutous at 
the apex ; eyes, ocelli, and valves of the terebra, black ; metathorax in 
one specimen rufous, black behind and at the lateral edges in both. 
Base of the petiole paler.
